Cronulla's Sione Katoa hobbled off with a groin injury during a 48-6 win over Canberra, raising fitness concerns.
Cronulla will be sweating on the fitness of Sione Katoa after he hobbled off with an apparent groin injury after an innocuous carry to sour their dominant win over Canberra.
The Sharks were way too good for an understrength Raiders side as they cruised to a 48-6 win in Gosford, with their halves controlling the contest a week after they performed well in the All Stars fixture.
But the focus will be on Katoa's fitness just days after false claims he'd suffered a serious shoulder injury, with Cronulla already missing superstar winger Ronaldo Mulitalo with a knee injury while playing for New Zealand.
Sam Stonestreet will replace Mulitalo on the left wing, with Mawene Hiroti the man most likely to come in for Katoa if he's unable to play in the early rounds.
Canberra's Matty Nicholson came off after a few minutes with what looked like a shoulder injury and didn't return.
